A new quantum spin liquid candidate for storage applications

At very low temperatures near the absolute zero, most of the matters will be freeze, hence the electrons become highly ordered. Quantum spin liquid is a novel phenomenon in which the electrons are entangled, but they remain fluctuating down to 0 K. A few quantum spin liquid materials have been reported and they have potential applications in data storage and memory. In this talk, I will present a new material, barium niobium iridium oxide-Ba4NbIr3O12, which can host a quantum spin liquid state, probed by magnetic susceptibility and heat capacity measurements. A comparison will be made to other related materials in the family.
